  • Patent number: 7791767
    Abstract: The present disclosure provides a repeated sampling method for image scanning. In one or more embodiments, the sampling method may comprise a sample treatment procedure for the data of an image scanning device during the scanning of an image. The method may comprise sampling, sorting, eliminating one or more group-departing values, and getting a mean value, etc. The sampling procedure may involve scanning a single point of the image several times to produce several sets of sampling values. The sorting procedure may involve sorting the several sets of sampling values after being sampled according to their magnitude. The eliminating group-departing values procedure may involve obtaining the relatively larger values and relatively smaller values from the several sets of sampling values after being sorted. The getting mean value procedure may involve obtaining a mean value from the several sets of sampling values.

  • Publication number: 20100214631
    Abstract: An image data sequencing method for a memory unit inside an optical scanning device. The image data sequencing method is particularly suitable for scanning a line of pixels with each pixel comprising a plurality of primary colors. The image data sequencing method involves scanning a line of pixels to obtain the data for a primary or secondary color. The pixels within the scan line are subdivided into groups. A storage space is reserved both before and after the address space inside the memory unit for holding the scanned primary or secondary color data so that all the primary or secondary color data constituting a pixel are in a fixed sequence next to each other inside the memory unit. When all the primary or secondary color data of pixels within a group are secured, the group of data is released from the memory unit.

  • Patent number: 7623735
    Abstract: A method for differentiating dynamic range of image is disclosed. The method comprises the following steps. First of all, pixel numbers with the same level value of Density units Dn-1 and Dn are compared. Next the minimum pixel number of each level value of Density units Dn-1 and Dn are counted. Then the minimum pixel numbers of each level value of Density units Dn-1 and Dn are summed. Next the ratio of total minimum pixel number and total pixel number R and a specification value Rs are compared. Then whether R is smaller than Rs or not is determined so as to recognize whether Density units Dn-1 and Dn could be differentiated or not.

  • Publication number: 20090147337
    Abstract: An opening method for a double-sided scanner is provided. A light source of one particular color inside a first group of light sources and a light source of a different color (or the same color) inside a second group of light source are lit to scan the front and back surface of a scan document. Optical signals from the front and back surface of the scan document are received and converted into analogue electrical signals. Thereafter, the analogue electrical signals are converted into digital electrical signal. Finally, the digital electrical signals are output to a host computer. This invention utilizes two groups of light sources (for example, light-emitting diodes) to serve as light sources for the double-sided scanner. Because light-emitting diodes require no warm-up period and is quick to switch, double-sided scanning is simplified.

  • Patent number: 7480420
    Abstract: A method for recognizing abnormal image is disclosed. The invention utilizes level comparisons of adjacent image lines to determine if there is any abnormal image amid an image picture and whether the abnormal image belongs to shading or LBB. The method comprises the following steps. First of all, two adjacent image lines having level values Pi and Pi?1 are selected. Then an absolute value of the Pi and the Pi?1 is calculated. Next the absolute value is compared with a value X. When the absolute value is smaller than X, then the image lines are determined as normal. On the contrary, when the absolute value is larger than X, then at least one of the image lines is determined as abnormal. Moreover, another two image lines having level values Pi+1 and Pi?2 separately adjacent the image lines having level values Pi and the Pi?1 are selected. An absolute value of the Pi+1 and the Pi?2 is calculated and the absolute value of the Pi+1 and the Pi?2 is compared to the value X.

  • Patent number: 7466869
    Abstract: The border of object in an image is blurred and so the modulation transfer function (MTF) of an image is reduced due to the blurred border. This present invention provides a deductive method for determining a border of an object in an image. Then the border of the object therein is amended and so the MTF of image is increased. In regard to an increasingly changeable color image, the present invention provides a deductive method in deciding upon a gray scale of the image to increase the color accuracy in amending an image.

  • Patent number: 7420715
    Abstract: In accordance with the present invention, a method and a system for promoting scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, adjusting system clock responsive to the transmission rate of the transit interface to change a data generated rate, and scanning an original to generate data at the rate controlled by the system clock. The key aspect of the present invention is by adjusting system clock to change the data generated rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the system clock is adjusted to produce the data at a rate that can reduce the possibility of memory buffer full leading to the reduction in the time wasting on start-stop processes and therefore promote the scanning speed without requiring the increase in size of a memory buffer.
